Getting Proper Speed on Dream Meter


Supposedly YES, if you pull the speedo gear and grind off one tooth it will be within 2-3 mph on the top end.

I wanted to ask this same question because I want to know if it ONLY fixes the top end and now down low it will be off or if its close from 0-120mph. Anyone know???
 
grinding off a tooth..

thats what you do when you go to 8 tooth drivers, not for stock 9 tooth drivers
 
IS that your final awnser? :) Doing some searching it looks like people have verfied the top speed with GPS with one tooth ground off and its around 2-3 mph accurate, which is impressive on snow and ice. I think I may do this, this winter. Anyone have a picture of what it should look like? Sounds simple enough I guess. Did Yamaha just not check the damn thing?
 
Just look at the pick-up wheel and you'll see it looks like the end of a splined shaft. Take it off and remove 1 of the splines. A cut off wheel works well. The whole speed thing is one issue, keep in mind if your speedo is reading 10% high so is your odometer.
 
Just wondering where is the pickup wheel, I'm a newbie at this and I have searched the online microfiche and I can't find it, so just wondering if I could get a quick explanation of where it is. Thanks

There is more info in the tech pages/Tech tips
 
Your jackshaft comes threw the tunnel under your clutch. Its bolted to the end of the jacksaft. There is a magnetic sensor bolted next to it that reads the teath. Reach under your clutch and you'll feel it.
